Question
A network engineer must configure a Fibre Channel interface on the Cisco MDS 9000 Series Switch. The configuration must meet these requirements:
- The interface must be disabled when the bit errors threshold Is
exceeded
- Buffer-to-buffer credits must be set to the maximum value
- The interface must have full bandwidth allocated for its port group
Which command set configures a Fibre Channel interface that meets these requirements?
Options
- Ainterface fc1/1
- Binterface fc1/1
- Cinterface fc1/1
- Dinterface fc1/1

Why each option
To configure a Fibre Channel interface on a Cisco MDS 9000 Series Switch with automatic disabling on error, maximum buffer-to-buffer credits, and full bandwidth allocation for its port group, the command `shutdown on error`, `buffer-to-buffer credits 255`, and `priority-group 1 bandwidth 100` are required.
The `shutdown on error` command ensures the interface is disabled if the bit error threshold is exceeded. `buffer-to-buffer credits 255` sets the buffer credits to the maximum supported value for Fibre Channel interfaces. The `priority-group 1 bandwidth 100` command allocates 100% of the bandwidth to priority group 1 for the port, fulfilling all three requirements.
If this option had any deviation from the correct command set shown in A, such as an incorrect buffer credit value or missing `shutdown on error`, it would be incorrect.
If this option had any deviation from the correct command set shown in A, such as incorrect bandwidth allocation or missing `no shutdown`, it would be incorrect.
If this option had any deviation from the correct command set shown in A, such as incorrect speed setting or an invalid FEC configuration, it would be incorrect.
